Abstract
The invention discloses a sensor combined with a power carrier. The sensor comprises a sensing module, an encoding and decoding module, a central processor, a filter and a power supply module, wherein signals collected by the sensing module are transmitted to a power supply module which couples the signals to a power line through the encoding and decoding module, the central processor and the filter. With the power supply module, the data signals are coupled to the power line for transmitting alternate current while the direct current power supply is supplied for the circuit, so that the cost is saved without paving the network data line again.
